Two-sided uniform air intake blower fan system of fume exhauster

Abstract

The invention relates to a uniform air intake draught fan system on double-side of a fume exhaustor, comprising a main unit, impeller and draught fan, a set of motor support frames are fixedly connected onto the motor, the motor support frame is fixedly connected onto the draught fan, the draught fan is fixedly connected onto the internal wall of the main unit, the impeller is connected to the output shaft of the motor, a communicated left air intake cavity and right air intake cavity are formed inside the main unit cavity. The impeller includes an upper loop, a central loop, a bottom loop and an impeller vane, the central loop is arranged between the upper loop and the bottom loop, an impeller frame for connecting the motor output shaft is fixedly connected onto the central loop. The invention has useful effect of: 1 effectively developing right side space of the draught fan system such that uniform air intake on double-side is obtained, easily absorbing oil smoke generated by a left boiler or right boiler in cooking process; 2 sufficiently developing right side area of the draught fan system to resolve bottleneck of improving air capacity such that air capacity is improved greatly.

Description

technical field [0001] The invention relates to a fan system of a range hood, in particular to a double-sided uniform air inlet fan system for a range hood. Background technique [0002] In the prior art, there are mainly two types of fans for range hoods. One is that the right side of the fan is completely sealed, and the air intake is all on the left side. The other type of fan also has an air inlet on the right side, and the motor is installed on the fan through a beam. However, due to the relatively large diameter of the motor currently used, the motor and the beam occupy most of the area of ​​the air inlet, resulting in the actual air intake from the right side of the fan. Therefore, the air intake effect of these two types of fans is not much different. The fan system composed of these two types of fans has common shortcomings: 1. The space on the right side of the fan system is not fully utilized, and the air volume cannot always be improved. 2. The air intake is unev...

The other type of fan also has an air inlet on the right side, and the motor is installed on the fan through a beam. However, due to the relatively large diameter of the motor currently used, the motor and the beam occupy most of the area of ​​the air inlet, resulting in the actual air intake from the right side of the fan. Therefore, the air intake effect of these two types of fans is not much different. The fan system composed of these two types of fans has common shortcomings: 1. The space on the right side of the fan system is not fully utilized, and the air volume cannot always be improved. 2. The air intake is uneven. , the left side is large, and the right side is small or none, resulting in the oil fume on the left being completely absorbed, and the oil fume on the right still exists

In addition, this impeller is also different from the previous impeller. The previous impeller is composed of an upper ring and a bottom ring. The bottom ring is formed by deep drawing, which occupies a large volume.
